This change fixes the NetApp promote back issue when using CIFS
protocol. When promoting a replica, the NetApp ONTAP driver
attempts to create a new CIFS share entity (an access point as
defined in [1]) for the new active replica. This behavior
causes a failure since the storage identifies that a current
backend CIFS share with the same name exists, considering
that the reffered replica was once the active one.
This issue is addressed by removing the related CIFS share
entity when the replica gets promoted.
